Tile Entity Not Saving Data

[cclloyd9785]

I'm having an issue where it doesn't seem to be saving the data for a tile entity when I quit the map.  Specifically it isn't saving the frequency if I set it (with a button on the guicontainer) then save and quit and reload.

 

Block: http://pastebin.com/nQdxYVHt

TileEntity:  http://pastebin.com/UH0a257v

GuiContainer:  http://pastebin.com/JTHrCWjc

Container:  http://pastebin.com/MumaxQyj

[TmzOS]

Try "worldObj.markBlockForUpdate(pos);" to update the block, or markDirty(), when you close/open the GUI (or ever if it is open).

 

Tip: http://www.minecraftforge.net/wiki/Tile_Entity_Synchronization

[cclloyd9785]

Doesn't seem to have worked.  And it got marked dirty when the frequency is set so it would've notice it there, but I did add it to an override method onGuiClosed() and it doesn't seem to have changed it.

 

Am I not writing to the NBT properly, or am I not writing to the actual tile entity?

[TmzOS]

See the link... you need to send description packets..

[cclloyd9785]

How would I go about that though.  Should I access the container that is the superclass of GuiContainer, since that half of it is server side?  Would changing that tile entity work? (Assuming I make it accessible by the guicontainer)

[TmzOS]

See the link... you need to send description packets..

No, this is not the issue here. Description packets go server to client.

Oh... fact... 

 

If the action is defined in the button see the part of client>server packet with the enchant button(It's for 1.7.10, maybe work for 1.8... ): http://www.minecraftforge.net/wiki/Tile_Entity_Synchronization

[cclloyd9785]

So I add an override enchantItem() into the Container.  I assume I ned to put

 

this.mc.playerController.sendEnchantPacket(container.windowId, action);

 

Into the GuiContainer.  But how do I access the container to get the windowId from the GuiContainer?

 

 

Edit:  I also tried doing this.wirelessChestEntity.freq(4000); in the onContainerClosed just to force it to do something on the container, and it still only is changed for the duration I'm in the game.  If I save and quit, it still resets to 0.

Hi

 

These links might help a bit with the background logic behind TileEntities and especially Containers

 

http://greyminecraftcoder.blogspot.com.au/2015/01/tileentity.html

http://greyminecraftcoder.blogspot.com.au/2015/01/gui-containers.html

 

Simple information can be sent from the server container to the client container using the crafters member variable of the container - icrafting.sendProgressBarUpdate() and icrafting.updateProgressBar() - if you are just sending a single number.

 

This tutorial project has a working example for 1.8, almost identical for 1.7.10.

https://github.com/TheGreyGhost/MinecraftByExample/tree/master/src/main/java/minecraftbyexample/mbe31_inventory_furnace

and especially

 

/* Client Synchronization */

// This is where you check if any values have changed and if so send an update to any clients accessing this container
// The container itemstacks are tested in Container.detectAndSendChanges, so we don't need to do that
// We iterate through all of the TileEntity Fields to find any which have changed, and send them.
// You don't have to use fields if you don't wish to; just manually match the ID in sendProgressBarUpdate with the value in
//   updateProgressBar()
// The progress bar values are restricted to shorts.  If you have a larger value (eg int), it's not a good idea to try and split it
//   up into two shorts because the progress bar values are sent independently, and unless you add synchronisation logic at the
//   receiving side, your int value will be wrong until the second short arrives.  Use a custom packet instead.
@Override
public void detectAndSendChanges() {
	super.detectAndSendChanges();

	boolean allFieldsHaveChanged = false;
	boolean fieldHasChanged [] = new boolean[tileInventoryFurnace.getFieldCount()];
	if (cachedFields == null) {
		cachedFields = new int[tileInventoryFurnace.getFieldCount()];
		allFieldsHaveChanged = true;
	}
	for (int i = 0; i < cachedFields.length; ++i) {
		if (allFieldsHaveChanged || cachedFields[i] != tileInventoryFurnace.getField(i)) {
			cachedFields[i] = tileInventoryFurnace.getField(i);
			fieldHasChanged[i] = true;
		}
	}

	// go through the list of crafters (players using this container) and update them if necessary
	for (int i = 0; i < this.crafters.size(); ++i) {
		ICrafting icrafting = (ICrafting)this.crafters.get(i);
		for (int fieldID = 0; fieldID < tileInventoryFurnace.getFieldCount(); ++fieldID) {
			if (fieldHasChanged[fieldID]) {
				// Note that although sendProgressBarUpdate takes 2 ints on a server these are truncated to shorts
				icrafting.sendProgressBarUpdate(this, fieldID, cachedFields[fieldID]);
			}
		}
	}
}

// Called when a progress bar update is received from the server. The two values (id and data) are the same two
// values given to sendProgressBarUpdate.  In this case we are using fields so we just pass them to the tileEntity.

And yet after I close the map it still doesn't save the frequency.  Only the items.

 

And just an FYI cause it doesn't seem clear, I am using MC 1.8.

[Abastro]

TGG already said how to do it.

You need to send the value of the field using icrafting.sendProgressBarUpdate in Container#detectAndSendChanges,

and override Contaier#updateProgressBar to update the field.

[TheGreyGhost]

If you are trying to send from the client to the server, you will need a custom packet.

For example, in GUIrepair.renameItem()

        this.mc.thePlayer.sendQueue.addToSendQueue(new C17PacketCustomPayload("MC|ItemName", (new PacketBuffer(Unpooled.buffer())).writeString(s)));

which is processed on the server in NetHandlerPlayServer.processVanilla250Packet(C17PacketCustomPayload packetIn)

        else if ("MC|ItemName".equals(packetIn.getChannelName()) && this.playerEntity.openContainer instanceof ContainerRepair)
        {
            ContainerRepair containerrepair = (ContainerRepair)this.playerEntity.openContainer;

            if (packetIn.getBufferData() != null && packetIn.getBufferData().readableBytes() >= 1)
            {
                String s = ChatAllowedCharacters.filterAllowedCharacters(packetIn.getBufferData().readStringFromBuffer(32767));

                if (s.length() <= 30)
                {
                    containerrepair.updateItemName(s);
                }
            }
            else
            {
                containerrepair.updateItemName("");
            }
        }

or for the example of a merchant trade

        else if ("MC|TrSel".equals(packetIn.getChannelName()))
        {
            try
            {
                int i = packetIn.getBufferData().readInt();
                Container container = this.playerEntity.openContainer;

                if (container instanceof ContainerMerchant)
                {
                    ((ContainerMerchant)container).setCurrentRecipeIndex(i);
                }
            }
            catch (Exception exception2)
            {
                logger.error("Couldn\'t select trade", exception2);
            }
        }

I think you will need to create your own custom packet and perform a container check (similar to above) on the EntityPlayerMP that you are given in the message handler.

Here's a working example of network messages that might help
